(AP) -- Park rangers found human bones in a remote area of Southern California's Joshua Tree National Park.
The National Park Service said over the weekend that there were no initial signs of foul play, but an investigation is ongoing.
The remains were first spotted during an analysis of photos taken in the area last summer. The area is remote, rocky and away from trails.
The park service was alerted last week, and rangers hiked to the area on Friday.
There they found human bones and personal belongings, but no ID.
It's not immediately clear how the person died.
